Yeah, whatever someone believe it or not but Libra is really bad news for bitcoin because Libra will surpass bitcoin easily.

I don't think so its 100% safe but we have no choice we have to use exchanges if we want to sell our coins. I transfer my coins to exchanges only when I want to sell otherwise I save my coins in Hardware wallet(Trezor). In the recent time binance also hacked so I feel no exchange is safe. Still I have trust on bittrex it is quite secured than other exchanges. Transaction fee you have to pay every time when you transact even you can check manually which exchange is taking less fee.

Well, you explain very well and appreciate you participate in this thread. Exchanges have a lot of problems include security, privacy, heavy fees, etc . so basically they are like a middle man. In 'atomic swaps' we can exchange our coins through our wallets directly which is a secure and more private way of exchanging, I just want to know your opinion on this what do you think which is a better way of exchanging 'atomic swaps' or Crypto exchanges?

There are no exchanges that can guarantee security 100% in the world. It is the fact and unavoidable, all crypto users must know about it.
Anyway, those exchanges should try their best to secure their members' assets but in the digital world, you cannot hope 100% secure for your assets. Regarding the fees, since there are a lot of exchanges, you can choose which one that is fit with your expectation, including the amount of fees.

You right very well I appreciate your participation this topic.  But do think security is the main concern for crypto users? Because all the well know exchanges get hacked in past and not just once. So, how do you think about this issue? and the 2nd thing I would like to ask exchanges is centralized so transactions are not private. So in the light of these issues don't you think "atomic swap" is a better solution? what do you think if we can exchange coins with privacy, security and without fees isn't it a better way of exchanging?

I never use bitcoin in my country for payment because my country is not much advance. But the blockchain industry is not that much old and people don't have much awareness about it but I hope in the upcoming years I can use it for payment purposes in my country also. In my opninon, it will still take 5 more years for this to happen.

Interesting question, first of all, joining crypto for Making money is also a big reason for me but I thought crypto is a newly established industry with a bright future. Crypto is growing rapidly and I don't want to miss this train. Along with money, there is another reason for me it offers multiple features like you know new projects are coming into the crypto world with many good features like privacy, mining, and many projects are offering privacy, mining, trading, business, etc. So for me, these are the few major reasons why I join crypto. I hope in future this growth in digital currency continues and it will be beneficial for all of us.

You should need to research for that I'm just giving away my personal idea about it. So, In my view, the coins with low capital are good to buy because they are cheap in price and will get good momentum when they gain some capital in the future and along with that Privacy coins are another option. They offer multiple features like privacy and trading at the same time also with that they offer mining features there are some coins who offer solo mining features. So, I think these are a good option to think about if someone interested in buying altcoins.
